A particular embodiment of this invention provides a combination method for producing town gas and benzene which comprises the steps of: (a) steam cracking a naphtha `fraction to produce a normally gaseous stream comprising carbon dioxide and a gaseous stream comprising at least by volume hydrogen; (b) catalytically reforming a naphtha fraction boiling between F. and 450 F. and containing primarily naphthenic and paraffinic hydrocarbons in the presence of at least a portion of said gaseous
gasoline and residual fuel oil in favor of middle distillates such as naphtha, diesel and jet fuel. Processing more unconventional oils, and the contaminants that come with them, brings more challenges to the present-day refiner, including downstream equipment corrosion, catalyst poisoning and the formation of green oils. Tighter
In the gasoline boiling range, these olefins have a high octane number and for the diesel fuel range product a high cetane number and low pour point following hydrogenation. Through normally designed to process propylene or butylene, MOGD is applicable to a wide range of feed streams ranging from ethylene to 400/sup 0/F endpoint olefinic naphtha.

TONSIL® JET SUPREME – THE GLOBAL BRAND FOR RELIABLE AND EFFICIENT JET FUEL AND KEROSENE PURIFICATION. Tonsil® Jet Supreme P is designed to remove the same compounds, however, even more efficient, with a significantly longer cycle life and the additional capability to remove color.
“From over 40 licensed waste oil recovery facilities in Malaysia, only one – ALDWICH – converts waste oil into diesel fuel.” Our plant is a refinery-caliber plant for processing waste oil and other hydrocarbons to value added products, primarily a middle distillate diesel conforming to ISO 8217 specification (grade DMA) for marine fuels.
Optimizing power generation from waste heat in large industrial facilities such as petroleum refineries by utilizing a subset of all available hot source streams selected based, in part, on considerations for example, capital cost, ease of operation, economics of scale power generation, a number of ORC machines to be operated, operating conditions of each ORC machine, combinations of them, or
The major hydrogen sources are natural gas, naphtha and coal. Most of the steam reforming plants use natural gas as feed stock. Natural gas contains fewer impurities, high hydrogen to carbon ratio and less percentage of higher hydrocarbons. So natural gas is superior when compared with other feed stocks.
Air Products operating experience with cryogenic hydrogen purification units is reviewed, including information on feedstock flexibility, turndown capabilities and response to plant upsets. Finally, an economic comparison of various methods of refinery off-gas purification is discussed.
